Webdithioethane were obtained from Sigma. AG 50W-X2 resin was obtained from Bio-Rad, HPLC-grade methanol was from American Scientific Products (Stone Mountain, GA), and constant-boiling HCI was from Pierce. Gramicidin A' was purchased from Sigma, and uniformly labeled ['5N]-gramicidin A' was prepared biosynthetically as described earlier (5). WebDec 1, 2010 · Weaker carbon nucleophiles such as 3,5-dimethoxyphenol and 3,5-dimethoxyaniline led to depolymerization products 4 and 5 but in lower yields. Both 4 and 5 could be modified further by protection of the catecholic units to give 6 and 7.In addition, 7 was readily converted into tridentate Schiff base, 8, in quantitative yield.The presence of …
